Abstract

The invention concerns a brush-holder plate and an electric motor comprising this brush-holder plate. The brushes of an electric motor are frequently ready-mounted on a brush-holder plate. However, the problem of keeping the brushes in the brush-holders before the collector is inserted frequently arises. It is already known to fit a retaining ring (10) in front of the brushes before the collector (3) is fitted, this retaining ring gradually being replaced by the collector (3) when the latter is fitted. The retaining ring (10) is introduced into a space provided for this purpose in the end shield (20). According to the invention, in order to hold the retaining ring (10) securely in the end shield space, the retaining ring has a slot (9) and is resilient in the radial direction. It can therefore bear with pretension against the outer walls of the accommodating chamber (25). Friction is produced between the ring (10) and the walls of the accommodating chamber (25), which prevents rattling or wear occurring as a result of movement of the retaining ring (10).

Description

Die Erfindung bezieht sich auf eine Bürstentrageplatte auf der Kocher befestigt sind, in denen Bürsten geführt sind, wobei die Führung der Bürsten unter Federbelastung in radialer Richtung auf einen zentralen Durchbruch in der Trageplatte hin erfolgt, mit einem radial federnden Haltering, wobei an der äußeren Mantel fläche die Bürsten anliegen und der Haltering in axialer Richtung verschiebbar ist.The invention relates to a brush support plate the stove is attached, in which brushes are guided, the guidance of the brushes under spring load in radial Towards a central breakthrough in the support plate with a radially resilient retaining ring, whereby the brushes rest on the outer surface and the retaining ring is displaceable in the axial direction.

Die Verwendung eines Halteringes zur Montagevereinfachung ist bereits aus der US 5 089 735 bekannt. Der Haltering befindet sich in einer Vormontageposition aufgespreizt zwischen den Bürsten und hält diese in einer zurückgeschobenen Position. Bei der Endmontage wird der Haltering durch das Einführen des Rotors mit dem Kollektor derart axial verschoben, daß die Bürsten auf die Kollektoroberfläche gelangen. Zwar ist der Haltering nach der Endmontage in einer Ausnehmung einer Halteplatte sicher befestigt aber diese Anordnung hat den Nachteil, daß sich der Haltering bereits vor der Endmontage ungewollt in axialer Richtung verschieben kann. Dies führt letztlich dazu, daß die Kohlebürsten unkontrolliert mit dem Kollektor in Kontakt gelangen, was Schwerwiegende Störungen des automatisierten Montagevorganges zur Folge hat.The use of a retaining ring to simplify assembly is already known from US 5 089 735. The retaining ring is located spread out in a pre-assembly position the brushes and keeps them in a pushed back Position. During final assembly, the retaining ring is replaced by the Inserting the rotor with the collector so axially shifted that the brushes get on the collector surface. The retaining ring is in a recess after final assembly a mounting plate securely attached but this arrangement has the disadvantage that the retaining ring is already in front of the Final assembly can move unintentionally in the axial direction. This ultimately leads to the carbon brushes becoming uncontrolled come into contact with the collector, which is serious Interferes with the automated assembly process.

Aufgabe der Erfindung ist daher, die Positionssicherheit der Montage von Bürstenhalteplatten zu verbessern.The object of the invention is therefore the positional security of the Improve assembly of brush holder plates.

Diese Aufgabe wird dadurch gelöst, daß der Haltering mit einer nach radial außen weisenden umlaufenden Kante versehen ist, welche in einer Vormontageposition an einer Grundseite der Kocher anliegt.This object is achieved in that the retaining ring with a circumferential edge pointing radially outwards which is in a pre-assembly position on a base side the cooker fits.

Mit den vorstehenden Merkmalen wird der Haltering in seiner Vormontageposition besonders einfach und kostengünstig festgelegt, weil keine gesonderten Bauteile benötigt werden. Dies ergibt sich dadurch, daß sich die umlaufende Kante unmittelbar an dem Haltering befindet und mit den Köchern zusammenwirkt.With the above features, the retaining ring is in its Pre-assembly position determined particularly easily and inexpensively, because no separate components are required. This results from the fact that the peripheral edge is immediate located on the retaining ring and interacts with the quivers.

Anhand von drei Figuren soll im folgenden ein Ausführungsbeispiel näher erläutert werden.

An exemplary embodiment will be explained in more detail below with reference to three figures.
Figure 1 and 2
show a brush support plate, wherein
Figure 1

Figure 2
shows a plan view of the brush support plate.
Figure 3
shows a cross section through an electric motor after assembly and the resulting new position of the retaining ring.

Zunächst wird auf die Figuren 1 und 2 Bezug genommen. Mit 1 wird die Trageplatte (Bürstentrageplatte) als Ganzes bezeichnet. Sie ist im wesentlichen kreisringförmig, das heißt ihr Außenrand ist der Kontur des Gehäuses des Elektromotors angepaßt, während der Durchbruch 2 kreisförmig ist und einen Durchmesser aufweist, der im wesentlichen dem Durchmesser des Kollektors 3 entspricht. Auf der Trageplatte sind mehrere Köcher 4 mit Bürsten 5 angeordnet.First, reference is made to FIGS. 1 and 2. With 1 the support plate (brush support plate) is referred to as a whole. It is essentially circular, that is its outer edge is the contour of the housing of the electric motor adjusted, while the breakthrough 2 is circular and one Has diameter that is essentially the diameter corresponds to the collector 3. There are several on the support plate Quiver 4 arranged with brushes 5.

Die Köcher 4 gruppieren sich konzentrisch um den inneren Durchbruch 2.The quiver 4 are grouped concentrically around the inner one Breakthrough 2.

Ein Köcher 4 ist üblicherweise aus einem vorgestanzten Blech gefaltet. Seine Außenkontur ist im wesentlichen quaderförmig, die vordere Stirnseite ist offen, so daß die eingesteckte Bürste 5 aus ihr herausragt.A quiver 4 is usually made of a pre-punched sheet folded. Its outer contour is essentially cuboid, the front end is open, so that the inserted Brush 5 protrudes from it.

Die hintere Seite ist durch eine Verschlußlasche 6 verschlossen. Zwischen der Bürste 5 und der Verschlußlasche 6 befindet sich eine Feder 7, die die Bürste 5 nach innen drückt und dafür sorgt, daß ein guter elektrisch leitender Kontakt zwischen der Bürste 5 und dem Kollektor 3 entsteht. Die Federn 7 bewirken, (wenn keine geeignete Rückhaltevorrichtung vorgesehen ist), daß die Bürsten vor dem Durchbruch gedrückt würden. Dies hätte zur Folge, daß die Bürstentrageplatte nicht auf den Kollektor 3 aufgeschoben werden könnte.The rear side is closed by a locking tab 6. Between the brush 5 and the locking tab 6 there is a spring 7, the brush 5 to the inside presses and ensures that a good electrically conductive Contact between the brush 5 and the collector 3 arises. The springs 7 act (if no suitable restraint is provided) that the brushes before the breakthrough would be pressed. This would result in the brush support plate could not be pushed onto the collector 3.

Um dies zu verhindern, ist ein Haltering 10 vorgesehen. Wie der Figur 1 zu entnehmen ist, hat der Haltering eine Höhe, die etwa der Höhe des Köchers 4 entspricht. In der gezeigten Position hat der Haltering einen Außendurchmesser, der im wesentlichen dem Durchmesser eines gedachten Kreises entspricht, an dem die inneren Stirnseiten der Köcher 4 angrenzen.To prevent this, a retaining ring 10 is provided. How 1 can be seen, the retaining ring has a height, which corresponds approximately to the height of the quiver 4. In the shown Position, the retaining ring has an outer diameter that is in the corresponds essentially to the diameter of an imaginary circle, on which the inner end faces of the quiver 4 adjoin.

Die Federn 7 drücken daher die Bürsten 5 gegen die äußere Mantelfläche des Halterings 10. Es wird damit verhindert, daß die Bürsten vor dem Durchbruch 2 geschoben werden. Der Haltering weist weiterhin eine umlaufende Kante 12 auf, die sich, wie die Figur 1 zeigt gegen die Grundseite 13 der Köcher 4 liegt, wobei die Grundseite der Köcher die Seite ist, die mit der Bürstentrageplatte verbunden ist.The springs 7 therefore press the brushes 5 against the outside Lateral surface of the retaining ring 10. This prevents that the brushes are pushed before breakthrough 2. Of the Retaining ring also has a peripheral edge 12 which as shown in Figure 1 against the base 13 of the quiver 4 lies with the base side of the quiver being the side which is connected to the brush support plate.

Die Figur 3 zeigt einen Elektromotor nach seiner Montage.Figure 3 shows an electric motor after its assembly.

Die Bürstentrageplatte 1 ist mit einem Lagerschild 20 verbunden. Dieses Lagerschild 20 ist Teil eines Gehäuses, das ein Getriebe oder eine Pumpe umschließt. Der Lagerschild 20 trägt ein Lager 21, durch das die Ankerwelle 22 des Elektromotors 23 hindurchgeführt ist. Auf der Welle 22 befindet sich der Kollektor 3 sowie die Rotorwicklungen 24. Diese sind mit dem Kollektor 3 verbunden. Der Elektromotor 23 weist weiterhin ein topfförmiges Gehäuse 24 auf, das auf den Lagerschild 20 aufsteckbar ist.The brush support plate 1 is connected to a bearing plate 20. This end shield 20 is part of a housing that encloses a gear or a pump. The end shield 20 carries a bearing 21 through which the armature shaft 22 of the electric motor 23 is passed. Located on the shaft 22 the collector 3 and the rotor windings 24 are connected to the collector 3. The electric motor 23 also has a cup-shaped housing 24 which on the Bearing plate 20 is attachable.

Im Lagerschild 20 ist ein Aufnahmeraum 25 vorgesehen. Dieser ist zylindrisch und öffnet sich zu der Seite des Schildes 20, das nach der Montage des Elektromotors in das Innere des Elektromotorgehäuses hineinzeigt.A receiving space 25 is provided in the end shield 20. This is cylindrical and opens to the side of the shield 20, which after mounting the electric motor inside the Electric motor housing shows.

Der Durchmesser des Aufnahmeraums 25 entspricht in etwa dem Durchmesser des Durchbruchs 2 in der Bürstentrageplatte. Da die inneren Enden der Köcher 4 etwas über die Kante des inneren Durchbruchs hinausragen, und der von ihnen eingeschlossene Kreis in etwa dem Durchmesser des Kollektors entspricht, ist der Durchmesser des Kollektors kleiner als der Durchmesser des Aufnahmeraums 25.The diameter of the receiving space 25 corresponds approximately to that Diameter of the opening 2 in the brush support plate. There the inner ends of the quiver 4 slightly over the edge of the inner one Breakthrough, and the one enclosed by them Circle corresponds approximately to the diameter of the collector, the diameter of the collector is smaller than that Diameter of the receiving space 25.

Zur Montage des Elektromotors wird zunächst das Lager 21 in die Lageraufnahme eingesteckt, die sich an den Aufnahmeraum 25 anschließt. Sodann wird die Bürstentrageplatte, falls sie nicht einheitlich mit dem Lagerschild ausgebildet ist, auf dem Lagerschild aufgesetzt. Dabei befindet sich der Haltering 10 noch vor den offenen Enden der Köcher 4, so daß die Bürsten nicht nach innen gedrückt werden können. Sodann wird die Ankerwelle 4 mit dem Kollektor 3 auf den Lagerschild aufgesteckt. Dabei legt sich der Kollektor 3 zunächst an den Haltering an und schiebt ihn gemäß der Darstellung der Figur 3 nach rechts. Der Kollektor 3 verdrängt dabei nach und nach den Ring und schiebt ihn in Richtung auf den Aufnahmeraum 25.To mount the electric motor, the bearing 21 is first in the bearing receptacle is plugged in, which is attached to the receiving space 25 connects. Then the brush support plate, if it is not formed uniformly with the bearing plate placed on the end shield. The retaining ring is located here 10 still before the open ends of the quiver 4, so that the Brushes cannot be pressed inwards. Then will the armature shaft 4 with the collector 3 on the end shield attached. Here, the collector 3 lies first on the Holding ring and pushes it as shown in the figure 3 to the right. The collector 3 gradually displaces it the ring and push it towards the recording room 25th

Der Kollektor 3 ersetzt somit nach und nach den Haltering 3, so daß sich die Bürsten 4 ohne daß sich ihre radiale Position ändert, in Kontakt gelangen mit dem Kollektor 3.The collector 3 thus gradually replaces the retaining ring 3, so that the brushes 4 without changing their radial position changes, come into contact with the collector 3.

Sobald der Kollektor 3 den Haltering 10 vollständig aus dem Bereich der Köcher 4 herausgedrückt hat, weitet er sich aufgrund seiner federnden Vorspannung auf und legt sich an die Seitenwände des Aufnahmeraums. Um die Aufweitung zu ermöglichen, ist der Haltering 10 geschlitzt (Schlitz 9).As soon as the collector 3 completely removes the retaining ring 10 from the Has pressed area of the quiver 4, it widens due to its resilient bias and lies on the Side walls of the recording room. To enable the expansion, the retaining ring 10 is slotted (slot 9).

Der Durchmesser des Aufnahmeraums und die radiale Federung des Halterings 10 sind derart aufeinander abgestimmt, daß der Haltering sich noch mit Vorspannung an die Wände des Aufnahmeraums 25 anlegt. Damit entsteht ein Reibschluß zwischen dem Ring und den Wänden des Aufnahmeraums, der dafür sorgt, daß der Ring unverrückbar im Lagerschild 20 liegt. Es können daher keine Klappergeräusche und kein unerwünschter Abrieb auftreten.The diameter of the receiving space and the radial suspension of the retaining ring 10 are coordinated so that the retaining ring is still attached to the walls of the Recording room 25 creates. This creates a frictional connection between the ring and the walls of the recording room that are there for ensures that the ring is immovable in the bearing plate 20. It can therefore no rattling noises and no unwanted Wear occurs.

Anschließend wird das topfförmige Gehäuse 24 auf das Lagerschild aufgesetzt und der Motor komplettiert.Then the cup-shaped housing 24 is on the bearing plate put on and the engine is completed.
